What Is the Best Way to Increase Multiple Server Performance ?

Question by Benito 911: what is the best way to increase multiple server performance ?
Hi, first of all, sorry for my bad english.
i’m in a school project on how to collaborate multiple servers to handle a single ultra-heavy-process, and i’ll be using linux.

well i’ve been searching for some time, and i found linux virtual server (www.linuxvirtualserver.org), cloud computing on ubuntu server, and some other server virtualization.

but.. as far as i can understand them, they use almost the same method of “load balancing” technique, which is looks like this link

so.. is there any other way to increase server performance, to be something like this :
if i’ve 3 servers, and each of them has 2 ghz of CPU speed, and 2gb of ram. so i’ll get 1 single super server (as virtual server) with 6 ghz of CPU speed and 6 gb of ram.

???

plus, i have another question..
1. what OS should i use?, if linux, which distro?, well, free is better..

any helps will be much appreciated…
Thanx !!..

Answer by pisces_ascendantI think you posted in hardware, and this is a software / OS question.

As far as hardware goes, upgrade to a SSD and you’ll notice a performance boost. That’s my two cents
